I have to be honest, looking through the bio I don't see anything that marks him to be... even as much of a threat as actual Emiya Shirou(Well, UBW or Heaven's Feel).

Unless there's something I'm missing? He seems pretty weak for a Servant and no worse then Raditz or even Black Rock Shooter, who's not exactly a powerhouse even if she's a dangerous fighter.

Like he's got a ton of mind trick stuff that lets him see through bad situations and plan things ahead, which is his strongest ability to be honest. His physical stats are below average for a servant, and he doesn't have the skill in combat of even an average servant(He's called an adept at the sword, slightly better than random Japanese rank and file soldiers, but definitely not a master which is what servants would be).  

I would say he is definitely stronger than Shirou just because he has servant level stats and both Eye of the Minds, which let him plan through and counter anything someone untrained like Emiya can do. In terms of raw firepower, he is below Emiya Shirou yeah. His main and unique ability is that he can hook up to other people's magic and then learn how to use it. So it'd be nifty to see him hook up his circuits to someone from another verse and then gain the ability to use magic from outside his verse.
